To all Il /LOH! it may concern:

Be it known that I, Amman I). Gaavns, of lloston, in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Wrapping-Machines, of which the following is aspecification, reference being had to the accompanying drawings, formingpart thereof.

This invention has reference to improvements in wrapping machines andparticularly to such machines adapted to receive a wrapper and a roll ofcandy wafers or lozenges, to apply said wrapper to said roll and to turnthe ends of said wra )per against the ends of said roll or against thearticles forming the ends of said roll.

One object of this invention is so to construct a wrappin machine of thenature herein described that one edge of'the wrapper ma be tuckedbeneath an overlapping edge hereof and said latter edge be smoothed intoposition.

Another object of this invention is so to construct a wra) ing machinefor a roll or stack of fiat artic es that the constituent elements ofsaid roll or stuck may be held together in alinement. during theapplication of the wrap or to the periphery of the roll or stuck anpreferably, until portions of the ends of the wrapper are turned inagainst the ends of said stack or roll.

Other objects of the .invention will appear from the following deserition.

The invention consists in he novel construction of the carrier frame androll enrrying devices mounted thereon.

The invention also consists in the novel means for applying the wrapperaround the roll.

The invention also consists in the means for holding the waters orlozenges in alinement.

The invention still further consists in such other novel features ofconstruction and combination of parts as shall hereinafter be more fullydescribed and pointed out in the claims.

Figure 1, represents a front elevation of the improved wrapping machinepartially broken away.and partially in section as taken on line 1--1Fig. 3. Fig. 2, represents an end view of the machine looking at it fromthe right hand end in Fig. 1, parts beingbroken away. Fig. 3, representsa vertical sectional view of parts of the machine taken on line 3%Fig. 1. Fl 4, represents a front view of ortions of the machine showingdetails 0 the tucking mechanism. Fig. 5, represents a sectional view ofparts of the same taken on line 5-5 Fig. 2. Figs. (3, 7, 8, and t) arediagrammatic views illustrating the turning in of the ends of the wraper.

Similar characters of reference designate corresponding arts throughout.

In carrying t 118 invention into practice I construct a machine havingthe end frames 11 and 12 connected by the tie rods 13, 13 and 14, 14 androvided with the table top 15 having the slot or opening 16 of a sizeand shape adapted to permit the passage therethrough of the roll A andits wrapper ll, indicated in Fig. 3 of the drawings.

Rotatably mounted in the frames 11 and 12 is the sleeve 17 on which ismounted and secured the carrier com risin the frame members 18 and 18 su)stantially of the shape shown in Fig. 3 and havin the radial arms 19,It) to which are secureil plates 20, 20 arranged in pairs connected bytroughs 21 and having the guide slots 22, 22 in which are slidahle theshafts 23, 23 having at their outer ends, outside said carrier frames18, 18 followers 24, 24 and the tucker plates 25, 25 the longitudinalslots of which are engaged with the guide pins 26, 26 of said plates 21.21.

Slidable transversely in each pair of said plates 21, 21 are the rackrods 27, and 28 raving respectively the pressers 29 and 30, provisionbeing made by the pinion 31, in engagement with the racks of said rods27, 28 to transmit motion from one of said rods to the other, and rod 27being provided with the spring 32 acting to move said rod in onedirection. Journaled in each pair of said plates 21, 21 are pairs ofshafts 33, 33 and 34, 34. On shafts 33, 33 at'the inner sides of plates21, 21 are mounted the arms 35, 35 connected in pairs by the curvedpressure plates 36, 36 while the outer ends of said shafts 33, 33 arefurnished with the arms 37 37 having the followers 38, 38. On shafts 84,34 are mounted the tucker arms 39, 89 having at their ends the tuckerplates 40, 40 while on the outer ends of these shafts 34, 34 af'niciuiftetf the arm S 41, 41having against the end of rack rod 27 untilthe )ackage or roll reaches the devices for turnmg? in the firstfolds'in the ends of the wrapper approximately at. which time thefollowers 42, 42 of arms 41,41 are engaged and actuated by the cam 44,also fixed to said frame member 12, while to both of said fr'ameniembers11 and 12 are fixed the proje'cto'r cam's'45, 45 and the retractor cams46,

46 adapted to engage and actuate the followers 24, 24 of shafts 23, 23.

, Mounted on the frames 11 and 12 are yielding bearings carrying thepressure rolls 47,, 47 which rolls are positioned to act against on'endof the" wrapper B during the passageof said rolls of the package Amovare with the" carrier.

The first folder or tu'cker devices 48, 48 are mounted on the' rockshaft 49 which is 26 m'ounted in the bearii'ig brackets 50, 50 of saidfi'an'ie's l1 and 12 and has, outside frame 12 ,"th'' lever arm 51connected by the pivoted link 52 with the sprin retracted lever 53m'ol'inted'to swing on said stud extending so fromsa'id frame 12. 7

Frame me her 12 has the slots 12', 12', through which extend pins 54, 54carrying a teninner ends the cam member 55 iavmg th internal cam 56 andthe external cam 57 which during the partial rotation of this cafnmember 55 acts against the followers 38, 38 of the arms 37, 37 to rocktheir shafts and to swing their pressure plates 36, 36 toward eachother. The partial rotation of earn member 55 is effected through thering 58 in which the outer ends of pins 54, 54 are securedand having thestuds 59 and 60, this riii 58 is journaled on'the sleeve of locking dist61 which is keyed to sleeve 17 and has ra dially extendingnotches 62,62, Figs. 2 and 5,ada'pte'd to be en aged by the bolt or latch 63shdable in gui es at the outer side of frair'ie 12 and 0130 ated by thebell crank lever 64, 05 connected with said latch 63 and pivotallymounted on a stud extending from frame member 12; spring 66 beingpr'pvided to act on said bell crank lever in the direction of engagementof latch 63.

Joui'naled in the bore of sleeve 17 is shaft 67 having at it's ends thetucker arms 68, 69

one of which has a limited movement between the steps 70 and 71 of framemember 12, and extending between these arms 68, 69 isthe tucker blade72which is actuated in 60 the direction in which the'package underoperation moves by said armsv68, 69. Pivot- ,mbiinted on the tucker arm,68wis the pawl' 73 hav ng the lever arm 74 which is ad pt'ed to beengaged, during thefih'al portion'of the forward movement of arm 68, byin 75 of frame member 12 at this time to disengage pawl 73 from theratchet disk 76 rotatable on said shaft 67 and having the pin 77 bywhich said disk 76 is connected with the arm 78 which latter isjournaled on the sleeve 17 between disk 61 and tucker arm 68. Pivotallymounted on arm 78 is pawl 79 having the member 80, said pawl 79 beingadapted, when moved forward to engage in one of the notches or sockets62 of the disk 61 to effect the intermittent rotation of said disk. Asthe first movement of arm 78, from the position shown in Fig. 2, isdownward said arm 78 strikes pin 60 of ring 58 and effects the swingingof said rin and cam member 55, attached thereto, to ring its cams 56 and57 between the followers 38, 38 of arms 37, 37 and to cause the swingingof said arms and the rocking of their shafts whereby the presser arms35, 35 and their plates 36, 36 are moved toward each other. At a pointin the forward, driving movement of arm 78 member 80 of its pawl 79strikes stud 59 of rim 58 and shifts said ring so that cam meni ber isshifted to move its cams 56, 57 from between the followers 38, 38 topermit the separating movement of plates 36, 36.

At the upper portion of frame 12 in alinement with rack rod 27 of theclosing device positioned to receive a roll and its wrapper is the aide82 having the slide 83 furnished at its mnerend with the head 84 andactuated by the arm 85 of the bell crank having the shaft 86 journaledin bearings mounted on frame 12 and having the arm 87 provided with theo )crating rod 88 havin the followers 89 and slidably engaged with thestud 90 of frame 12 on which stud is journaled the gear 91 having thecams 92 and 93 of which cam 92 is adapted to act at each rotation ofgear 91 against followers 89 of rod 88 to effect the lifting of said rodand, through its connections therewith, the actuation of the slide rod83, while cam 93 acts against the lower end of pivoted arm 52 to causethe swinging of said arm to swing the first folders 48, 48 over the endsof a package positioned relative thereto. When rack rod 27 is ushedinward by the head 84 of the slide rot 83 said rack rod is adapted to heheld inward by cam 43 of frame 12 during the rotation of package carrierfrom the receiving position approximately to the first folding position.

Gear 91 is driven by gear 94 journaled on a stud extending from frame 12and having cam 95, to act against lever arm 5 and effect the releasingmovement of latch 63 from latch disk 61, and stud 96 which is connectedby the pivoted rod 97 with a similar stud on the pawl arm 78, thesemembers bein so timed as to their operation that latch 3 is releasedfrom disk before stud 96 reaches a position to act, through rod 97, toswing pawl arm upward and to eifectthe intermittent-rotation of latchdisk 61 and sleeve 17, to which said disk is keyed, with the carrierframes 18, 18 mounted on said sleeve.

Gear 94 is driven by pinion 98 mounted on shaft 99 which is journaled inbearings and is driven in a suitable manner, the proportions of said ear94 and pinion 98 being such that pimon 98 rotates more rapidly than gear94 and preferably makes two or more rotations for each rotation of gear94. With one of the receptacles or troughs 21 and its related mechanismin position beneath the slot or opening 16 of table 15, a wrapper B isplaced on said table over said opening and a stack or roll A of wafersor lozenges is placed on said wrapper and pressed downward with the saidwrapper through the said opening to the position indicated in dottedlines in Fig. 3. This placing of the roll A and its wrapper B in thereceptacle 21 is timed with relation to the operation of the machinewhich now acts by means of cam 92 on the followers 89 of the rod 88 toswing the bell crank having arms 87, 85 to move slide rod 83 inwardwhereby the head 84 of said rod pushes rack rod 27 and said motion istransmitted by pinion 31 to rack rod 28 so that the pressers or heads 29and 30 respectively of said rods are brought to bear against the ends ofthe stack of wafers or the articles to hold said wafers or articlestogether in stack form. At.- or about this time cam 95 of gear 94 actsagainst lever to effect its release of latch 63 from the notch or latchdisk 61 whereby said disk is free to rotate. The rotation of gear 94 inthe direction indicated by its arrow effects, through rod 97, first aretractive movement of pawl arm 78 until said arm engages pin 60 of ring58 and causes the shifting of said ring whereby the cam member 55,connected with ring 58 by pins 54, 54. is also shifted to bring itsearns 56 and 57 to act against followers 38, 38 thus moving saidfollowers to cause the rocking of the shafts 33, 33 and the swinging ofthe arms 35, 85 to bring their presser plates 30, 36 against the wrapperas indicated in Fig. 6. As, under the continued rotation of gear 94,pawl arm 78 is moved upward said arm through its pin 77 effects therotative movement of ratchet disk 76 and such movement is transmitted bypawl 73 to its tucker arm 68 whereby both of said tucker arms are swungand tucker 72 is advanced to tuck down the rear end of the wrapper B, asindicated in Fig. 7, and as this application is accomplished cam member74 rides on to pin whereby pawl 73 is disengaged from ratchet disk 76and the tucker arms 68, '68 are free to move backward under theretraction of their spring. At or about the accomplishment of thistucking 0 eration pawl 79 of arm 78 engages one 0 the notches 2 in latchplate 61 and etl'ects'the rotative movement of said plate and the sleeve17 with the parts attached thereto. In such movement the end of rod 27moves off of pusher head 84 and is engaged by cam 43 which prevents itsoutward movement of said rod 27, the roll A and its wrapper is carriedbeneath rolls 47, 47 which roll down the final edge of the wrapper andas the rod 27 moves by the end portion of cam 43 the spring of said rod27 causes it to move outward and said motion of this rod is transmittedby pinion 31 to red 28 whereby the pressers 29 and 30 are moved out ofthe way to permit at this time, the infolding of end portions of thewrapper, see Fig. 8, by the first folders 48, 48 the followers 42, 42 ofthe side folders or second and third folders 40, 40 are engaged andactuated by cam 44 whereby said folders 40, 40 are swung to the positionshown in Fig. 9 to fold inward portions of the wrapper and subsequentlythe followers 24, 24 of shaft 23 ride over the proiector cams 45, 45 andeffect the projection of the fourth folder plates 25, 25 to the positionindicated in dotted lines at the left hand side of Fig. 3 making thefinal folds in the ends of the wrapper. Thereafter cams 46, 46 actagainst said followers 24, 24 to retract shaft 23 and its folder blades25, 25 while pawl arm 78 moves to a position to engage member of itspawl 79 with stud 59 of ring 58 whereby said ring and cam member 55,connected therewith are shifted to release cams 56 and 57 from thefollowers 38, 38 of the presser plates 36, 36 so that said nressers mayseparate to permit. the discharge of the wrapped roll or package. Aseach of the notches 62 of the plate 61 is brought into registry withlatch 63 said latch engages therewith and locks the package carriermechanism against rotation.
